Top US aide Sullivan calls for return of Northern Ireland devolution
A senior member of the American government has urged Northern Ireland's politicians to sort out a deal to restore powersharing.
John Sullivan, the acting US Secretary of State, was speaking to mark the 20th anniversary of the Good Friday Agreement.
He said Northern Ireland had travelled far, but challenges still persist.
The comments represent a rare intervention from the Trump administration in Northern Ireland politics.
Mr Sullivan has been acting US Secretary of State since Rex Tillerson's departure last month.
In a statement released by the State Department in Washington, he said: "The Good Friday Agreement, endorsed widely by the people of the region, remains an inspiration around the world.
"As we reflect on this important anniversary, let us remind ourselves - and the generations since the signing in 1998 - of how far the people of the region have travelled, as well as the challenges that persist.
"We encourage all parties in Northern Ireland to work together to form a regional, power-sharing government that benefits all the people of the region."
The US government played a key role during the peace process in the 1990s.
However, American involvement has declined in recent years.
